Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep -- about 100 to at least 500 feet below the surface -- little to no light breaks through.
Researchers must rely on submersible watercraft or sophisticated diving equipment to be able to study ocean life at these depths, known as the mesophotic zone. These deep areas span the world's oceans and are home to extensive coral reef communities, though little is known about them because it is so hard to get there.
Neuroscientists at the RIKEN Center for Brain Science (CBS) and University College London have found an anatomical link between cognitive and perceptual symptoms in autism. Published in the Journal of Neuroscience, the study identified a posterior region of the brain whose size--amount of gray matter--is related to both cognitive rigidity and overly stable visual perception, two symptoms of autism that until now were only conceptually related.
CORVALLIS, Ore. - New strategies for river management are needed to maintain water supplies and avoid big crashes in populations of aquatic life, researchers argue in a perspective piece published today in Nature.
The scientists say a fresh approach is necessary as the climate warms, which has led to historic die-offs like the January 2019 event in the Murray-Darling Basin of Australia that saw severe water shortages bring hardship to residents and kill millions of fish.
A team of researchers led by a member of the Colorado School of Public Health faculty at the Anschutz Medical Campus examined what type of social interaction is required for people to display physiological synchrony--mutual changes in autonomic nervous system activity. The study also looked at whether the levels of autonomic arousal people share predicts affiliation and friendship interest between people.
The findings are published in Nature Scientific Reports.
Blockchain Technology is known to be one of the top disruptive technologies of today that is driving the fourth industrial revolution. A blockchain, designed to be resistant to the modification of its data, offers security and privacy benefits that are well appreciated particularly by banks, governments and techno-corporations.
Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarisation of radio waves within it for the first time - moving us closer to an understanding of what causes the universe's most powerful explosions.
Gamma Ray Bursts (GRBs) are the most energetic explosions in the universe, beaming out mighty jets which travel through space at over 99.9% the speed of light, as a star much more massive than our sun collapses at the end of its life to produce a black hole.
Sigma receptors are proteins found on mainly the surface of endoplasmic reticulum (ER) in certain cells. Sigma-1 and sigma-2 are the two main classes of these receptors. The sigma-1 receptor is involved neurological disorders and certain types of cancer. To understand better how the receptor is involved in disease and whether drugs developed to target it are working, it is important to be able to accurately trace the sigma-1 receptor. Researchers at Kanazawa University have developed a probe, which can identify and latch onto the sigma-1 receptor.
A new platform for speeding up and controlling the evolution of proteins inside living plants has been developed by a KAUST-led team.
Previously, this type of directed evolution system was only possible in viruses, bacteria, yeast and mammalian cell lines. The Saudi research--part of KAUST's Desert Agriculture Initiative--has now expanded the technique to rice and other food plants. It means that plant breeders now have an easy way to rapidly engineer new crop varieties capable of withstanding weeds, diseases, pests and other agricultural stresses.
The relation between collagen laxity and anxiety in humans is widely known, but this relation has never been observed before in other species. A team of researchers led by professors Jaume Fatjó and Antoni Bulbena from the Department of Psychiatry and Legal Medicine at the UAB, the Hospital del Mar Medical Research Institute (IMIM) and the UAB Affinity Foundation Chair in Animals and Health, analysed a set of 13 animal behaviour characteristics and hip joint mobility in a total of 5575 domestic dogs.
The secret of platinum deposits revealed by novel field observations in the Bushveld Complex
Most of the world's economically-viable platinum deposits occur as 'reefs' in layered intrusions - thin layers of silicate rocks that contain sulphides enriched in platinum group elements which are so vital for the sustainable development of modern human society.
The rise of dating websites and apps have changed the dating scene, leading singles to make judgments on potential dates as fast as they can swipe their screen. With about 20 million baby boomers actively using at least one of these dating services, they want to look their best and feel confident in the modern dating world. New statistics released by the American Society of Plastic Surgeons finds more Americans age 55 and older are seeking out cosmetic procedures, with nearly 50,000 more procedures performed on patients in this age group in 2018 than the previous year.
Almost 500,000 Americans die each year from cardiac arrest, when the heart suddenly stops beating.
People experiencing cardiac arrest will suddenly become unresponsive and either stop breathing or gasp for air, a sign known as agonal breathing. Immediate CPR can double or triple someone's chance of survival, but that requires a bystander to be present.
CINCINNATI -- Scientists at Cincinnati Children's Hospital Medical Center have identified an expression pattern of 14 genes at the time of diagnosis that predicts two year, transplant-free survival in children with biliary atresia - the most common diagnosis leading to liver transplants in children.
The researchers also found that the antioxidant N-acetyl-cysteine (NAC) reduced liver injury and fibrosis (excess fibrous connective tissue) in mice with biliary atresia and increased survival times.
As automation advances, predictions of a jobless future have some fearing unrest from mass unemployment, while others imagine a more contented work-free society.
Aside from economic factors, paid employment brings other benefits - often psychological - such as self-esteem and social inclusion. Now, researchers at the universities of Cambridge and Salford have set out to define a recommended "dosage" of work for optimal wellbeing.
Atrial fibrillation (AF) is linked to an increased risk of dementia, even in people who have not suffered a stroke, according to the largest study to investigate the association in an elderly population.
In addition, the study, which is published in the European Heart Journal [1] today (Wednesday), found that AF patients who took oral anticoagulants to prevent blood clots had a decreased risk of dementia.
